Could '8080' cause redirection problems?

I running several sites under Laragon and only now I have noticed that one of them has ':8080' added to its URL. I don't quite exactly know what it is and why only this one. At the same time, I am running a Wordpress with a page builder - Elementor. One of my portfolio widgets can redirect elements like images to custom URLS. While I need it to reach external sites, I also need it to redirect internally. However, when I do that, the redirector always lands on the homepage ignoring any sub-pages. Could the 8080 be messing up with it or is it more likely that widget simply cannot handle internal URLs?
